First Embodiment
[0016] FIG. 1 is a vertical sectional drawing of a hoistway of an
elevator system to which a marking positioning device for an
elevator according to a first embodiment is applied.
[0017] In the elevator system in FIG. 1, a hoistway 1 pierces
through floors of a building. Each of a plurality of halls 2 is
provided at each floor of the building. Each of the plurality of
halls 2 faces the hoistway 1. For example, in a case of an elevator
having two doors which face each other and an elevator having two
doors which are perpendicular to each other, each of the plurality
of halls 2 faces the hoistway 1 at each floor of the building.
[0018] When an elevator is, for example, newly constructed, renewed
or renovated, a marking positioning device 3 measures a
three-dimensional shape inside the hoistway 1 while flying inside
the hoistway 1. The marking positioning device 3 makes marks for
hammering anchor bolts, or the like, at designated positions inside
the hoistway 1 while flying inside the hoistway 1.
[0019] For example, the marking positioning device 3 performs
marking while flying inside the hoistway 1 on the basis of the
designated positions set by a mobile terminal 4 of a worker.
[0020] The marking positioning device 3 will be described next
using FIG. 2.
[0021] FIG. 2 is a perspective view of the marking positioning
device for an elevator according to the first embodiment.
[0022] As illustrated in FIG. 2, the marking positioning device 3

a plurality of wing support portions 3c, a plurality of leg
portions 3d, a power supply unit 3e, a plurality of detecting units
3f, a measuring unit 3g, a marking unit 3h, a communication unit
3i, and a control unit 3j.
[0023] For example, the body portion 3a is formed in a columnar
shape. The plurality of rotary wing portions 3b are provided to
rotate so that the body portion 3a can fly. The plurality of wing
support portions 3c are provided so as to be able to respectively
support the plurality of rotary wing portions 3b. The plurality of
leg portions 3d are provided so as to be able to support the body
portion 3a upon landing of the body portion 3a.
[0024] For example, the power supply unit 3e is provided inside the
body portion 3a. The power supply unit 3e is provided so as to be
able to supply power necessary for operation of the marking
positioning device 3. For example, the power supply unit 3e is a
storage battery which stores power from outside.
[0025] For example, the plurality of detecting units 3f in a first
set are provided at equal intervals near an edge portion on an
upper surface of the body portion 3a. For example, the plurality of
detecting units 3f in a second set are provided at equal intervals
near an edge portion on a lower surface of the body portion 3a.
Each of the plurality of detecting units 3f is provided so as to be
able to detect a position of the body portion 3a. For example, each

rangefinder, an altimeter, or the like.
[0026] For example, the measuring unit 3g is provided on a side
surface of the body portion 3a. The measuring unit 3g is provided
so as to be able to measure a three-dimensional shape inside the
hoistway 1. For example, the measuring unit 3g is a device
including an RGB camera and an infrared camera.
[0027] For example, the marking unit 3h is provided on the lower
surface of the body portion 3a. The marking unit 3h is provided so
as to be able to perform marking. For example, upon contact with an
object, the marking unit 3h is provided so as to be able to perform
marking by attaching a marking material to the object while
absorbing a shock with elastic force. For example, the marking unit
3h is provided so as to be able to perform marking by causing a
paintball filled with a marking material to hit the object. For
example, the marking unit 3h is provided so as to be able to
perform marking by spraying a marking material to the object as
being performed by a spray gun configured with a nozzle, a
compressed gas and a paint bottle.
[0028] For example, the communication unit 3i is provided on an
upper surface of the body portion 3a. The communication unit 3i is
provided so as to be able to wirelessly exchange information with
external devices.
[0029] For example, the control unit 3j is provided inside the body
portion 3a. The control unit 3j is provided so as to be able to
wholly control the marking positioning device 3.
[0030] For example, the control unit 3j is provided so as to be
able to control flight of the marking positioning device 3 in
front-back and right-left directions by changing pitch angles of
the plurality of rotary wing portions 3b with the plurality of wing
support portions 3c. For example, the control unit 3j is provided
so as to be able to control flight of the marking positioning
device 3 in an up-down direction by changing rotation speed of the
rotary wing portions 3b.
[0031] For example, the control unit 3j controls flight of the body
portion 3a on the basis of the position detected by the detecting
unit 3f so that a position of marking by the marking unit 3h is
located at a designated position set in the three-dimensional shape
measured by the measuring unit 3g.
[0032] For example, the control unit 3j is provided so as to be
able to calculate the designated position on the basis of
information on the three-dimensional shape measured by the
measuring unit 3g and information on design of the elevator. In
this calculation, a model of a car guide rail 5 which guides a car
6 which is not illustrated, a dimension of travel of the elevator,
a dimension of a total height of the hoistway 1, a dimension in a
width direction of the hoistway 1, a dimension in a depth direction
of the hoistway 1, a direction of the hoistway 1, and the like, are
taken into account as the information on the design.
[0033] For example, the control unit 3j is provided so as to be
able to recognize a structure of the elevator on the basis of the
three-dimensional shape measured by the measuring unit 3g and
control flight of the body portion 3a using the structure as a
standard so that the position of marking by the marking unit 3h is
located at the designated position on a wall surface of the
hoistway 1.
[0034] For example, the control unit 3j determines whether or not
the position of marking recognized by the measuring unit 3g is
located at the designated position set in the three-dimensional
shape.
[0035] An example of the standard for positioning marking will be
described next using FIG. 3.
[0036] FIG. 3 is a front view of a hall of an elevator to which the
marking positioning device for an elevator according to the first
embodiment is applied.
[0037] When the elevator is, for example, newly constructed, a
structure is not positioned inside the hoistway 1 which is not
illustrated in FIG. 3. In this case, as illustrated in FIG. 3, an
edge portion of an entrance of the hall 2 is set as a structure
which becomes a standard for positioning marking. The marking
positioning device 3 recognizes both edge portions in a width
direction of the entrance of the hall 2 on the basis of the
three-dimensional shape measured by the measuring unit 3g while
flying inside the hoistway 1. The marking positioning device 3 sets
the center of the both edge portions in the width direction of the
entrance of the hall 2 as the standard for positioning.
[0038] Outline of operation of the marking positioning device 3
will be described next using FIG. 4.
[0039] FIG. 4 is a flowchart for explaining outline of operation of
the marking positioning device for an elevator according to the
first embodiment.
[0040] In step S1, the marking positioning device 3 measures the
three-dimensional shape inside the hoistway 1 while flying. The
marking positioning device 3 then performs operation in step S2. In
step S2, the marking positioning device 3 calculates the designated
position in the three-dimensional shape.
[0041] The marking positioning device 3 then performs operation in
step S3. In step S3, the marking positioning device 3 controls
flight on the basis of the designated position. The marking
positioning device 3 then performs operation in step S4. In step
S4, the marking positioning device 3 determines a position of
marking while flying.
[0042] According to the first embodiment described above, flight of
the marking positioning device 3 is controlled so that the position
of marking is located at the designated position set in the
three-dimensional shape. It is therefore possible to easily perform
marking at the designated position inside the hoistway 1.
[0043] Further, the designated position is calculated on the basis
of information on the measured three-dimensional shape and
information on design of the elevator. It is therefore possible to
appropriately perform marking in accordance with an actual
situation of the elevator.
[0044] Further, flight of the marking positioning device 3 is
controlled using the structure recognized on the basis of the
measured three-dimensional shape as a standard. Specifically, the
center of both edge portions in the width direction of the entrance
of the hall 2 is set as the standard of positioning. It is
therefore possible to perform marking more appropriately in
accordance with an actual situation of the elevator.
[0045] Further, the marking positioning device 3 determines whether
or not the position of marking is located at the designated
position. It is therefore possible to easily recognize whether or
not marking is appropriately performed.
[0046] Note that upon renewal, renovation, or the like, in a case
where a jamb is left at the edge portion of the entrance of the
hall 2, the center of both edge portions in a width direction of
the jamb may be set as the standard for positioning. Also in this
case, it is possible to perform marking more appropriately in
accordance with an actual situation of the elevator.
[0047] Further, upon renewal, renovation, or the like, in a case
where a hall door for opening and closing the entrance of the hall
2 is left, the center of the hall door may be set as the standard
for positioning. Also in this case, it is possible to perform
marking more appropriately in accordance with an actual situation
of the elevator.
[0048] Further, upon contact with an object, the marking
positioning device 3 attaches a marking material to the object
while absorbing a shock with elastic force. It is therefore
possible to suppress wobbling of the marking positioning device 3
upon marking.
[0049] Further, the marking positioning device 3 shoots a paintball
filled with a marking material. It is therefore possible to perform
marking without contacting a portion where the marking positioning
device 3 is to perform marking.
[0050] Further, the marking positioning device 3 sprays a marking
material. It is therefore possible to perform marking without
contacting a portion where the marking positioning device 3 is to
perform marking.
[0051] Note that marking may be performed through irradiation of
lower-power laser light. In this case, it is possible to perform
marking more accurately.
[0052] Note that power supply and information exchange may be
performed in a wired manner. Also in this case, it is possible to
easily perform marking at the designated position inside the
hoistway 1.
[0053] Further, the marking positioning device 3 may be remotely
operated on the basis of an external signal. Also in this case, it
is possible to easily perform marking at the designated position
inside the hoistway 1.
[0054] Further, information indicating the designated position set
by the mobile terminal 4 of the worker may be wirelessly received
at the communication unit 3i, and the designated position may be
set on the basis of the information. Also in this case, it is
possible to easily perform marking at the designated position
inside the hoistway 1.

[0057] The support portion 3k is provided at the hall 2 so as not
to drop inside the hoistway 1. For example, the support portion 3k
is formed in a bar shape so as to be hooked at both edge portions
of the entrance of the hall 2. The projecting portion 3l is
connected to the support portion 3k. The projecting portion 3l is
provided so as to project to inside of the hoistway 1. The
connecting portion 3m is formed in a string shape. The connecting

[0058] According to the second embodiment described above, the body
portion 3a is connected to the connecting portion 3m. The
connecting portion 3m is connected to the projecting portion 3l.
The projecting portion 3l is connected to the support portion 3k.
The support portion 3k is provided so as not to drop inside the
hoistway 1. It is therefore possible to prevent the marking
positioning device 3 from dropping inside the hoistway 1. As a
result, it is possible to prevent equipment inside the hoistway 1
from being damaged due to drop of the marking positioning device
3.
Third Embodiment
[0059] FIG. 6 and FIG. 7 are vertical sectional drawings of a

[0063] Upon renewal, renovation, or the like, the pair of car guide
rails 5 and the car 6 are sometimes left. In this case, as
illustrated in FIG. 6, marking is performed at the upper portion of
the hoistway 1 while the car 6 is evacuated to the lower portion of
the hoistway 1. As illustrated in FIG. 7, marking is performed at
the lower portion of the hoistway 1 while the car 6 is evacuated at
the upper portion of the hoistway 1.
[0064] An example of the standard for positioning marking will be
described next using FIG. 8.
[0065] FIG. 8 is a cross-sectional view of the hoistway of the
elevator system to which the marking positioning device for an
elevator according to the third embodiment is applied.
[0066] In a case where the pair of car guide rails 5 and the car 6
are left upon renewal, renovation, or the like, as illustrated in
FIG. 8, one of the pair of the car guide rails 5 is set as a
structure which becomes a standard for positioning in a depth
direction of the hoistway 1. One side surface of the car 6 is set
as a structure which becomes a standard for positioning in a width
direction of the hoistway 1. The marking positioning device 3
recognizes one of the pair of car guide rails 5 and the one side
surface of the car 6 while flying inside the hoistway 1. The
marking positioning device 3 sets the recognized one of the pair of
car guide rails 5 and one side surface of the car 6 as the
standards for positioning.
[0067] According to the third embodiment described above, the car
guide rails 5 are set as the standard for positioning. It is
therefore possible to perform marking more appropriately in
accordance with an actual situation of the elevator.
[0068] Note that it is also possible to set a weight guide rail
which guides a counter weight as the standard for positioning. Also
in this case, it is possible to perform marking more appropriately
in accordance with an actual situation of the elevator.
[0069] Further, the body portion 3a is connected to the connecting
portion 3o. The connecting portion 3o is connected to the gripping
portion 3n. The gripping portion 3n grips the car guide rail 5. It
is therefore possible to prevent the marking positioning device 3
from dropping inside the hoistway 1. As a result, it is possible to
prevent equipment inside the hoistway 1 from being damaged due to
drop of the marking positioning device 3.
[0070] Note that the gripping portion 3n may grip the weight guide
rail. Also in this case, it is possible to prevent the marking
positioning device 3 from dropping inside the hoistway 1. As a
